Switching off the Smart Line Module:
To switch off the active line module, carry out the steps for switching it on in re-
verse order.
Switching off the controller with the OFF1 signal is delayed by the time entered in
p3490, thereby allowing the connected drives to be decelerated in a controlled
manner.
